Specification forming part of Letters Patent No. 129,284, dated July 16, 1872.

Having thus described my invention, I claim as new and desire to secure by Letters Patcut-- The method of producing a fine giltfinish on zinc, tin, or analogous metals by polishing the metal between the coppering and lacquering processes, as described, whereby the same effect is produced as by a gold-gilding, and at less than one-fifth of the cost.
